Bananas are my staple food, have been for many years. Cheapest by the pound for number of calories, easiest to eat during the day while training & working, available in all grocery stores...

I like mine a bit soft w/ brown spots & definitely much more when there's no green. I don't think it really hurts too much to eat them when there's a little green in them. A little starchy tasting imo, not as sweet. Some folks might say that they are harder to digest when green. They're even harder to peel when green. :)
